Gurus,
sed -e "s/\(.\{1,255\}\)\(.\{1,2\}\)\(.*\)/\1AB\3/" FILE ---this works
sed -e "s/\(.\{1,468\}\)\(.\{1,2\}\)\(.*\)/\1AB\3/" FILE ---this does not
It works only till 1,255 ( any number below 255 works)
Any one know how to increase this limit.
Thanks

ppmtopj(1) General Commands Manual ppmtopj(1) NAME
ppmtopj - convert a portable pixmap to an HP PaintJet file SYNOPSIS
ppmtopj [-gamma val] [-xpos val] [-ypos val] [-back dark|lite] [-rle] [-center] [-render none|snap|bw|dither|diffuse|monodither|monodif- fuse|clusterdither|monoclusterdither] [ppmfile] DESCRIPTION
Reads a portable pixmap as input and converts it into a format suitable to be printed by an HP PaintJet printer. For best results, the input file should be in 8-color RGB form; i.e. it should have only the 8 binary combinations of full-on and full-off primaries. You could get this by sending the input file through ppmquant -map with a map file such as: P3 8 1 255 0 0 0 255 0 0 0 255 0 0 0 255 255 255 0 255 0 255 0 255 255 255 255 255 Or else you could use use ppmdither -red 2 -green 2 -blue 2. OPTIONS
-rle Run length encode the image. (This can result in larger images) -back Enhance the foreground by indicating if the background is light or dark compated to the foreground. -render alg Use an internal rendering algorithm (default dither). -gamma int Gamma correct the image using the integet parameter as a gamma (default 0). -center Center the image to an 8.5 by 11 page -xpos pos Move by pos pixels in the x direction. -ypos pos Move by pos pixels in the y direction.
